Abstract
Hydrogen and carbonyl sulfide are produced by a process comprising contacting gaseous hydrogen sulfide with gaseous carbon monoxide in the presence of a precious metal promoted multi-metal oxide/sulfide catalytic composition, e.g. a catalyst of the formula: Ag.sub.0.1 Ni.sub.0.45 Cu.sub.0.45 MoO.sub.x S.sub.y.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A process for the production of hydrogen and carbonyl sulfide, the process comprising contacting gaseous hydrogen sulfide with gaseous carbon monoxide in the presence of a catalytic amount of a composition of the formula: M.sub.0.1-2 M'.sub.0.01-1 M".sub.0.01-1 O.sub.x S.sub.y (I) where M is at least one of Mo, W and Fe; M' is at least one of Ru, Rh, Ag, Pt, Pd, Au, Re, Os and Ir; M" is at least one of V, Cr, Ti, Co, Ni and Cu; and the sum of x+y is a number that satisfies the valence requirements of the other elements present.
2. The process of claim 1 where M is one of molybdenum and tungsten.
3. The process of claim 1 where M' is at least one of silver, ruthenium and platinum.
4. The process of claim 2 where M' is at least one of silver, ruthenium and platinum.
5. The process of claim 1 where M" is at least one of nickel and copper.
6. The process of claim 2 where M" is at least one of nickel and copper.
7. The process of claim 3 where M" is at least one of nickel and copper.
8. The process of claim 4 where M" is at least one of nickel and copper.
9. The process of claim 1 where the composition of formula I is used in combination with a support.
10. The process of claim 4 where the composition of formula I is used in combination with a support.
11. The process of claim 8 where the composition of formula I is used in combination with a support.
12. The process of claim 9 where the composition of formula I is present in an amount of at least about 10 weight percent, based on the combined weight of the support and the composition.
13. The process of claim 10 where the composition of formula I is present in an amount of at least about 10 weight percent, based on the combined weight of the support and the composition.
14. The process of claim 11 where the composition of formula I is present in an amount of at least about 10 weight percent, based on the combined weight of the support and the composition.
15. The process of claim 1 where the subscript value of M is about 0.5 to about 1, of M' about 0.01 to about 0.5 and of M" about 0.25 to about 1.
16. The process of claim 4 where the subscript value of M is about 0.5 to about 1, of M' about 0.01 to about 0.5 and of M" about 0.25 to about 1.
17. The process of claim 8 where the subscript value of M is about 0.5 to about 1, of M' about 0.01 to about 0.5 and of M" about 0.25 to about 1.
18. The process of claim 11 where the subscript value of M is about 0.5 to about 1, of M' about 0.01 to about 0.5 and of M" about 0.25 to about 1.
19. The process of claim 14 where the subscript value of M is about 0.5 to about 1, of M' about 0.01 to about 0.5 and of M" about 0.25 to about 1.
20. The process of claim 19 where the support is a high, surface area gamma-alumina.
21. The process of claim 1 wherein M' is at least one of Ru, Ag, Au, Re, Os and Ir.Cited by (0)
